[Abstract]:Polycarbonate (PC) is a kind of glassy amorphous polymer which is widely used in military and industrial fields because of its excellent heat resistance and impact resistance. In this paper, the mechanical properties of polycarbonate amorphous polymers are reviewed. The experimental results are analyzed from the phenomenological point of view, and the mechanical properties of these materials are revealed. Secondly, the development history, physical mechanism, mechanical properties and applicable range of various constitutive models of this kind of materials are introduced. Finally, the applications of various constitutive models in polycarbonate polymer materials are summarized, and the characterization of mechanical behavior of materials by constitutive models is further discussed from the point of view of engineering application. At the same time, the key scientific problems and further research prospects of polycarbonate materials in experimental and theoretical research are also given.
